The urban areas in the country are populous with high population density in the expansion of urban areas into the fallow and virgin lands around them because of the increasing population and migration of the people from one place to another.
Construction of roads and buildings as facilities for local people and acts of humans and vehicles cause damage to existing natural situations, harming the environment to be polluted.
The high density of population brings hotness to the urbanites. The small and large cities full of public housing emit heat into the atmosphere, which reflects the climatic conditions of the country. Air-conditioners, refrigerators and other electronic equipment, as well as vehicles and industries, release gases, smoke and heat to the urban areas.
The high temperature of urban areas may bear physical and mental harmfulness to the people of urban areas. In summer, the people may suffer from harmful impacts over emergency health cases such as muscle cramps, heat stroke, heart attack, as well as respiratory tract diseases based on dust, smoke, gases and various kinds of pollution.
The best way to prevent the environmental overheating is to grow trees in harmony with urban buildings and roads. In this regard, it is necessary to culture lawns and grows flowery parks and shade trees without covering the concrete structures such as buildings, streets and car parks around the urban area in order to control the heat and reflection, absorb gases such as carbon dioxide, sustain moisture in the shade of trees and make the air quality good.
Moreover, the greening structures and activities created with flowery plants and shade trees help the people be clean and fresh, easing their tensions triggered by depression of the people from the workplaces and restricted daily routines.
These will be challenges to increasing population density in urban areas and the booming of major cities in the future. Despite natural situations, relevant authorities need to manage the relaxation of overheating and air pollution based on the spreading of mist, dust, smoke and dangerous gases. To mitigate these impacts, all citizens need to grow various species of trees in vacant and virgin lands inside and outside the cities.
Only when urbanites in all counties establish the green cities will the planet Earth have a chance to extend its term of age. Consequently, all global people will have the opportunity of accommodation. If so, all need to create a green country and a green Earth for future generations.
